Overview

Attaches the invoking shell's stdin, stdout and stderr to the container specified as argument.

The attachment will succeed only if the target container was started in interactive mode:

docker run [-d] -i alpine ash

Then, the attachment can then be performed with:

docker attach <container-id>

Starting the container in detached mode is optional, docker attach can attach to a non-detached container as well. In that case, two shells (the one from which docker run was executed and the one from which docker attach was executed) will be attached at the same time to the container.
